Warsaw  - Poland's finance ministry sold euros on the market Wednesday from its European Union funds amid a sinking zloty, a ministry spokesman told TVN24.

The spokesman declined to say how much was sold, or if the government would sell more in an effort to boost the weakening national Polish currency.

The zloty had dipped to 4.94 against the euro on Tuesday. It had risen to 4.77 against the euro at the close of the stock exchange on Wednesday.

Polish Prime Minister Donald Tusk said on Tuesday that the government would intervene if the country's currency dropped to 5 zloty against the euro. The announcement came after the zloty dropped to historic lows.

Poland joined the European Union in 2004, and is expected to replace its national currency with the euro by 2012. (dpa)
